　　In the lifting of lifting hooks, the hook often rotates. When the lifted heavy object is lifted, the hook will rotate, the wire rope between the pulley set hanging on the top of the hook and the boom will twist, and the lifted heavy object will rotate with the hook. At this time, it is no longer possible to continue to lift or put down the lifted heavy object. The hook rotation seriously affects the normal progress of lifting operations and seriously threatens the safety of operating personnel and equipment. It must be prevented.

　　The reasons for the rotation of the hook are internal and external factors of the crane, while the internal factors of the rotation of the hook are the fundamental reasons.

　　The wire rope used in cranes, regardless of its model, specification, or grade, will generate force when subjected to stress. The wire rope is first twisted spirally into a thread, and then several threads are twisted spirally into a thread. After the stress is applied, the wire and steel strands will be straightened, but in the lifting course, the ends of the wire rope are fixed torques that make the hook assembly tend to rotate.

　　But on the other hand, there are many external factors that directly cause the hook to rotate. For example, during the lifting process, external forces such as human or wind force push the hook to swing, and the hook interpolation method leads to imbalance in the hook, etc.

　　The rotation of the hook is related to the following factors:

　　1. The larger the crane, the higher the lifting height, that is, the longer the length of the wire rope between the top pulley set and the hook, the greater the possibility of the hook rotating.

　　2. It is easier to rotate the hook by winding the hook into a single array than a double array, and the number of matching wire ropes is smaller, making the hook easier to rotate.

　　3. The larger the weight of a single wire rope, the more likely it is to hook and rotate.

　　4. The smaller the shape and pulley size of the hook assembly, the more likely it is to rotate the hook;

　　The speed of operating the lifting and landing hook of the crane is unstable, especially after the hook with a larger weight is off the ground, the possibility of rotation increases.

　　5. The speed of operating the lifting and landing hook of the crane is unstable, especially after the hook with a larger weight is off the ground, the possibility of rotation is greater.

　　The above are some reasons why the lifting hook will rotate when used. You can find out if you have any questions or needs. You can consult and contact us at any time!
